Title: Solid phase system incorporating tetrazolium salts for use in ligand-receptor assays
Inventor: ANDERSON RICHARD R
IPC: G01N33/569
Filed: 1987-07-06
Granted: 1991-10-01
Abstract: ABSTRACT           A solid phase system incorporating a tetrazolium salt for use in a ligand receptor assay for the detection of a selection analyte in fluid sample is disclosed, wherein the tetrazolium salt functions to augment the color development of the indigogenic enzyme substrates used in such assays.  The solid phase system comprises a solid support on which is localized in the same area a receptor and a tetrazolium salt.  Methods for localizing the receptor on the solid support include chemical coupling and entrapment of receptor coated microspheres.  The tetrazolium salt may be localized on the solid support by adsorption by hydrophobic interaction with the solid support or by entrapment of tetrazolium salt coated microspheres. The solid phase system is useful when incorporated in an apparatus for conducting ligand receptor assay processes.  The use of the solid phase system in immunoassays and nucleic acid assays are described.

Title: Edge illuminated impurity band conduction detector arrays
Inventor: BHARAT RAMASESHA
IPC: H01L31/10
Filed: 1988-02-26
Granted: 1991-05-07
Abstract: ABSTRACT    An edge illuminated optical detector array includes a series of two or more detectors which operate under an applied electric field.  Each detector includes an extrinsic semiconducting active layer with a first conductivity type impurity concentration high enough to create an impurity energy band, and an intrinsic semiconducting blocking layer in which substantially no charge transport occurs by an impurity conduction mechanism.  The detectors are positioned relative to one another such that optical energy incident on the array and directed substantially orthogonal to the applied electric field impinges on the first detector in the series and the portion of the optical energy which is transmitted by each detector is directed to the succeeding detector in the series.          In this manner, the spectral content of the optical energy impinging on each detector is modified by the spectral transmission characteristics of the preceding detectors.    In a solid state photomultiplier detector embodiment, each detector also includes an extrinsic semiconducting buffered layer having a first conductivity type impurity concentration which is high enough to create an impurity energy band and a second conductivity type impurity concentration which is high enough that first conductivity type carriers injected into the buffered layer recombine with ionized first conductivity type impurities. Each active layer also includes a second conductivity type impurity concentration which is low enough that first conductivity type carriers photogenerated in the active layer can drift through the active layer without recombining with ionized first conductivity type impurities.

Abstract: METHOD FOR MANAGEMENT OF LOGICAL CHANNELS FOR             ISDN PACKET SERVICE                ABSTRACT OF THE DISCLOSURE    A method for management of logical channels essen-tial for packet communication between an ISDN and subscribers.  An ISDN cannot maintain details on each of the number of pieces of data terminal equipment in each subscriber.  Therefore, the data terminal equipment returns to the ISDN the logical channel group number (LCGN) which has been allotted to itself upon receipt of a package at the ISDN.  The ISDN then refers to the logical channel management memory corresponding to the specified data terminal equipment using that LCGN, while the data terminal equipment refers to the logical channel management memory in its own terminal adapter, with both thus obtaining the information required for the start of the packet communication.   Further, when forming in the ISDN a logical channel management memory corresponding to a newly established data terminal equipment, direct registration is performed directly between the ISDN and data terminal equipment automatically for the LCGN, etc.

Title: Tamper indicating package
Inventor: KELLER ROBERT G
IPC: B65D55/06
Filed: 1988-03-16
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE       The tamper indicating package includes a receptacle, such as a jar having a cover member threaded thereon. The mouth of the jar is sealed beneath the cover member with a seal member. The cover member has a depending flange with a slot that accommodates a tab indicating member joined to the seal member or formed integrally with the seal member. Rotation of the cover member from a predetermined closed limit position causes the slot in the cover member to interfere with the tab indicating member. The interference causes partial or complete severance of the tab indicating member from the seal member, providing a visible indication of previous tampering with the package.

Title: Furnace burner block
Inventor: MCNALLY THOMAS A
IPC: F23M5/00
Filed: 1988-06-28
Granted: 1991-02-26
Abstract: ABSTRACT OF THE DISCLOSURE      The burner block or tile in industrial furnaces is conventionally made of refractory ceramic material. Such refractories are susceptible to cracking from thermal shock if the temperature of the burner block fluctuates during use.  The life of the burner block can be greatly improved by making it in two parts:  a cavity bounding inner part made from a material more shock re-sistant than a conventional refractory and a convention-al refractory outer part.  Best results are obtained with a thin inner liner of recrystallized silicon car-bide having a thermal conductivity of over 18 W/(m K) and a modulus of rupture of at least 120 MPa.

Title: Supercharging pressure control method for internal combustion engines
Inventor: INOUE KAZUO
IPC: F02B37/12
Filed: 1988-12-28
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE        A method of controlling supercharging pressure in an internal combustion engine wherein the supercharging pressure created by a supercharger is controlled based on a basic control amount determined in dependence on operating conditions of the engine. The basic control amount is corrected in response to a difference between an actual value of the supercharging pressure and a desired value of same when the engine is in a feedback control region. The basic control amount is corrected in accordance with the change rate of the supercharging pressure when the engine is in an operating condition immediately before the feedback control region.  The supercharging pressure is controlled based upon a second basic control amount other than the first-mentioned basic control amount when the supercharging pressure is below a predetermined value determined by the engine rotational speed and the change rate of supercharging pressure in the above operating condition.  The feedback control is started on condition that the actual supercharging pressure has increased above a second predetermined value set depending upon operating parameters of the engine and a parameter representative of an environmental condition of the engine.  The feedback control is started when a predetermined period of time has elapsed after the supercharging pressure has increased above the second predetermined value.  The feedback control is effected when the supercharging pressure is in a steady state, while the supercharging pressure is controlled in open loop mode when it is in a transient state.

The microprocessor actuation and control means provides a calibration mode and a normal mode of operation. During the normal mode of operation, a frequency hopping rate on the order of four thousand hertz is achievable. The method of interdiction comprises the steps of generating and storing voltage control words for operating the oscillators consistent with a head end selected jamming factor for a particular channel to be jammed and addressably transmitted and stored premium program-ming authorization data.
